a friend of mine just called in, on his way back from a National Norton Motorcycle Rally, to show me his completely restored ex RAF Police Norton, he bought it some time ago, and it needed a lot of work, which he has now done.  It is a 1985 model, and was, apparently, used for escorting duties before being retired to recruiting duties, and was displayed at shows around the country.   We would welcome any information on this, or a similar model, from anyone who may have any service knowledge of them.   Sadly, nothing as posh as this in my day, electric self-starting etc.
